Lesson: Interactions of Electromagnetic Waves with MatterPhysics
In this lesson, we will learn how to describe the effects of different types of electromagnetic waves on matter, including their effects on the human body.

- The radiation must be weakly absorbed by plastic.
- The radiation must be strongly absorbed by plastic.
- The critical angle for the radiation at the boundary between the plastic of the cores must be large.
- The critical angle for the radiation at the boundary between the plastic of the cores must be small.
